To all whom it may concern:

Be it known that we, GEORGE D. B. PRES- corr and MELVIN A. NowELL,citizens of the United States, residing at Concord, in the county ofMerrimac and State of New Hampshire, have invented certain new anduseful Improvements in Metal Frames for Pianos; and we do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and' -otherwise fall wholly upon said wrest-block,which is ordinarily composedof a single piecel of timber. These veneersare secured together and to the wrest-plank by glue and are placed oneupon another, having their grain running alternately in oppositedirections; and Various means have been employed as a partial assistanceto the glue for retaining said veneers in place, and it is to thisfeature in piano construction to which our present invention moredirectly applies.

To this end our invention consists in providing a metallic frame ofproper form to accommodate veneers extending to top of frame, and thusaffording additional means for-retaining them in place providing theglue fails to wholly perform its duty, which will be fully set forth inthe following specification and claims, and clearly illustrated in theaccompanying drawings, forming a part of the same, of which- Figure l isa broken elevation showing the upper portion of our improved metallicframe, the pin-block, and a few of the strings and tuning-pins in properposition, Fig. 2 being a longitudinal section showing the metal of theframe on line WV WV, Fig. l. Fig. 3 is a vertical section taken on linex oc, Fig. 1. Fig. 4

is a vertical section at line y fg, Fig. 1; and Fig. 5 is a verticalsection taken at z z, Fig. l.

Similar reference-letters designate correspending parts throughout thevarious views. A represents the upper part of the metallic frame, havingthe openings a and a near its top, as shown, and through which in Fig. lY

may be seen, respectively, the veneers B b, forming the pin-block andwhich are attached to the wrest-plank C. That metal of the frame A whichis above the openings a a is not on an'equal plane with the metal belowsaid openings, as shown best in Figs. 3, fi, and 5, that shown at CL2,directly over the opening ct, being brought. forward sufficiently tocause its rear face to be flush with the front metal below said opening,while that shown at a3, which is over the opening o, is broughtsufficiently forward to cause its rear face to be [iush with the frontface of the metal a2. This offset inthe metal above these openings isalso clearly shown in Fig. 2, in which the bridge o4 for thebass-strings and that portion 0.5 of the frame forming a seat for thebase of the wrest-plank are best shown. Thus it will be seen that aframe of our improved construction allows. of covering the entire frontlsurface of the wrest-block C with the layers of veneer B, and alsopermits of applying additional layers of veneers b for the tuning-pinsof thebass-strings, all of which extend from the seat a5 to the eXtremeupper edge of the frame, thereby obtaining the maximum glue surface, thefull clasping strength of the upper portion of said frame, and utilizingthe bolts and screws, respectively, D d as additional means of holdingthe pin-block, said bolts and screws passing through said veneers intothe solid wrest-plank and serving to tightly clasp the same.

Having described our invention, what we claim as new is- Y 1. A metalframe for pianos provided with offsets in its rear face, and openings insaid offsets for the reception o f the tuning pins, the rear face of oneof said offsets being on a plane with the forward face of the other,substantially for the purpose set forth.

2. A metal frame for pianos provided with an opening for the tuning'pins of the treble strings the metal above said opening; being setforward as shown, and an opening for the tuning pins ofthe bass strings,the metal above said opening forthe bass strings being sei. forwardsul'lieiently to cause its rear face to be on a plane with the forwardface of that metal above the opening for the tuning,r pins of the treblestrings, all substantially for the purpose set forth.

3. A metal frame for pianos having oponings, one for all the tuning pinsof the treble strings, and one for all those of the bass strings, andhaving the metal above said openings set forward sufficiently to causethe rear
